Hi, I can reproduce the problem with version 1.3.x, or with version 1.4.x when disabling the MVStore (append ";mv_store=false" to the database URL). With version 1.4.x (beta), that is with the MVStore, it does not occur.
I'm not quite sure what the problem is, it looks like the LOB is removed a bit too early. What is easy to change is the error message (it should say "Missing lob entry"), but I'm not sure how to best fix the problem.
